For professional use, that's it! Enough for a year before repairing the anchor or replacing the bearing of the gearbox (during everyday work, a total of one hour per shift). All employees of the enterprise are very satisfied. I bought ALL similar angle grinders with similar characteristics and handle design - only Makita is the longest-playing one. The experience of using such grinders is about 5 years. During this time, dozens of these grinders passed through the hands of the workers, and they all went for at least a year before the first repair (!)
